Description

Plug connector assembly with modular plug-in contact and coding element

Technical Field

The invention relates to a plug connector assembly.

Background

The assembly includes a holding frame configured to receive frame openings of a plurality of modular plug-in contacts at a plurality of insertion locations arranged in a row with one another along a width direction. At least one modular plug-in contact can be inserted into the frame opening in order to form a plug-in surface on the fixing frame in at least one insertion position. The fixing frame has at least one frame wall extending in the width direction and configured with an accommodation opening corresponding to the insertion position. The at least one modular plug-in contact then has a housing body and at least one coding element section corresponding to the housing body for engagement in one of the receiving openings of the at least one frame wall in the inserted state of the at least one modular plug-in contact in the frame opening.

Such a holding frame serves to accommodate a plug-in contact in a modular manner on a plug connector. One or more plug-in contacts can be placed on such a holding frame so that they can be inserted together with the holding frame into the housing of the plug connector and connected to the housing. In this way, the plug-in contacts can be combined with one another in a modular manner and can be arranged in or on the plug connector by means of the fixing frame.

Such a plug-in contact can, for example, have one or more electrical contacts. In this case, the plug-in contact is connected on the one hand to an electrical line which is introduced into the plug connector and on the other hand forms a plug-in contact, by means of which the plug connector can be plugged into electrical contact with the counter-plug connector.

Such modular plug-in contacts offer the advantage of flexible assembly and variable suitability for plug-in connectors.

Plug connectors with a retaining frame for receiving modular plug contacts are known, for example, from DE 102012110907 a1 or DE 202012103360U 1.

In the fixing frame known from DE 102012110907 a1, it is provided that a second fixing frame part can be mounted on a first fixing frame part having a receiving opening for receiving the coding element of the plug-in contact, so that the coding element inserted into the receiving opening is locked in this way and is thus locked on the fixing frame.

The coding element serves to ensure that the modular plug-in contact is correctly mounted in the insertion position of the fixing frame. In particular, the coding elements of the modular plug-in contact are preferably designed such that the modular plug-in contact can only be mounted in exactly one orientation and position in the plug-in position.

The modular plug-in contact can have a width (viewed in the width direction) which is equal to the width of the insertion site. However, it is also conceivable and possible for the modular plug-in contacts to have a width which differs from the insertion position and in particular has a width which differs from an integer multiple of the width of the insertion position, for example a width which is half the width of the insertion position. In this case, the modular plug-in contacts can be combined with one another for installation in the insertion position, which means that the coding element sections of the modular plug-in contacts are, if necessary, inserted together into corresponding receiving openings of an insertion position.

In this case, it is desirable for the modular plug-in contacts to be able to be combined with one another flexibly.

Disclosure of Invention

The object of the invention is to provide a plug connector assembly and a method for configuring a plug connector assembly which allow a modular plug-in contact to be variably assembled for installation in an insertion position of a frame opening of a fixed frame.

This object is achieved by a body having the features of the assembly of a plug connector according to the invention.

Accordingly, at least one encoding element segment can be adjusted.

In conventional plug-in contacts, the variable combination of modular plug-in contacts for the common insertion into the insertion position of the fixed frame can interfere with the fixed placement of the coding element on the housing body of the modular plug-in contact. In the combination of plug-in contacts with one another, it must therefore be noted that the coding element sections of different plug-in contacts are mounted on one another and cooperate with one another in such a way that, when the combination of plug-in contacts is inserted into the insertion position of the fixed frame, the coding elements formed by the coding element sections of the plug-in contacts engage in a defined manner with the receiving openings in the frame wall of the fixed frame.

By making the coding element section of the modular plug-in contact adjustable, plug-in contacts for common insertion into the insertion position can be variably combined with one another. In particular, the coding element can be adjusted according to the combination of the plug-in contacts in order to achieve a defined engagement in the receiving opening in the wall of the fixed frame, for example when a combination of two modular plug-in contacts with a half width (compared to the insertion position) is jointly inserted into the insertion position.

In this case, different markings can also be provided on different coding element sections, so that different markings on the plug-in contact can be provided by the variable application of different coding element sections. The identification on the plug-in contact can thus be carried out in a simple manner by adjusting and, if appropriate, replacing the coding element section.

A variety of variants for providing adjustability of one or more coding element sections on the modular plug-in contact are conceivable and possible.

In one embodiment, the at least one coding element section is present independently of the housing body in the pre-configuration state. In order to configure the plug-in contact, one or more coding element sections can be mounted on and connected to the housing body, so that the coding elements on the plug-in contact are provided in this way. The plug-in contact can therefore be variably equipped with coding element sections, so that the plug-in contact can be configured with different coding element sections.

The connection of the coding element section to the housing body of the plug-in contact can be effected, for example, in a form-fitting manner, for example, by means of a connecting device formed on the housing body, by means of which the coding element section can be connected to the housing body in a form-fitting manner.

For example, the connecting device can provide a push connection of the coding element section to the housing body. The coding element section can be pushed onto or into the connecting device preferably in the width direction.

The positive connection between the coding element section and the housing body can be made, for example, in that the engagement section of the coding element section is pushed into a push-in opening on the housing body. The coding element section is preferably formed as a single piece with the coding element section, and the coding element section is preferably formed as a single piece with the coding element section.

Additionally or alternatively, the coding element section can have a push-in opening which pushes on an engagement section on the housing body so as to be connected to the housing body. On the other hand, a form-fitting connection between the coding element section and the housing body is established, but in this case by engagement of the engagement section of the housing body in the insertion opening of the coding element section.

In one embodiment, the connecting device of the housing body has both the insertion opening and the engagement section, and the corresponding coding element section has the engagement section and the insertion opening, respectively. For the connection, the coding element sections are mounted on the housing body such that the engagement sections engage with one another in the corresponding insertion openings.

In a further variant, the coding element section can have a connecting pin which can be inserted into a connecting opening on the housing body. In this case, the connection is not effected by pushing or pushing in the width direction, but rather by pushing or pushing in the plugging direction transversely to the width direction. The connecting bolt preferably provides a pivot about which the coding element section can be rotated relative to the housing body when it is mounted on the housing body. The adjustment of the coding element provided by the coding element section can be carried out for the purpose of configuring the plug-in contact by rotating the coding element section on the housing body. The coding element segments, as viewed in the width direction, can cover different width ranges depending on their rotational position and can thus be adjusted for engagement in receiving openings of different widths on the frame wall of the fixed frame.

When the coding element segments are mounted on the housing body of the plug-in contact, each coding element segment preferably protrudes from the housing body and is thereby placed on the housing body to provide a coding. In this case, it is conceivable that, when the coding element section is connected to the housing body, it bears against a projection section which projects from the housing body, in particular is formed integrally with the housing body, and, together with the projection section, provides the coding on the housing body. In this case, different projection sections, in particular projection sections of different widths (viewed in the width direction), or projection sections on one side and projection sections on the other side can be provided on different side walls of the housing body, so that coding elements of different widths can be formed on different side walls by the interaction of the coding element sections with the projection sections on different sides of the housing body. This makes it possible to use similar coding element sections on both side walls of the housing body, wherein different codes on the side walls are realized by the shape of the raised sections.

Instead of being configured by means of a different coding element section that can be variably mounted on the housing body of the plug-in contact, adjustability can also be provided in that the coding element section has a target division position for dividing a partial region of the coding element section. The width of the coding element section can thus be varied in the width direction depending on such a target division position, so that a matching with a corresponding receiving opening of the frame wall of the fixed frame is thereby carried out.

Such adjustability, which is achieved by dividing and removing partitions of the coding element segments at the target division locations, can be provided on a coding element which is constructed integrally with the housing body. However, it is also conceivable and possible to provide this adjustability on the coding element section which is to be connected in a form-fitting manner to the housing body of the plug-in contact.

In one embodiment, the housing body has two opposite side walls, each of which is associated with a coding element section. In this case, the coding element segments can be connected to the corresponding side walls in a form-fitting manner, wherein for this purpose connecting means are arranged on the respective side walls, which achieve a form-fitting connection.

The connecting devices on the different side walls are preferably designed such that only the coding element section specifically corresponding to this side wall can be mounted on each connecting device. In this way, only a specific coding element section corresponding to the connecting device can be mounted on the connecting device of the first side wall. On the other second side wall, only a further coding element section corresponding to this further connecting device can be mounted on the contrary. This ensures that different codes are implemented on different side walls, each having a clearly corresponding coding element section.

In a further embodiment, the coding element segments to be mounted on different side walls of the housing body are connected to one another by clamping plates and thus form a uniform element that can be mounted on the housing body. The clamping plate can be designed such that it clamps the housing body (when the elements of which the coding element section is a part are mounted on the housing body) around the housing body, for example above or on the side of the housing body. In this case, a combination of coding element sections for mounting on the housing body of the plug-in contact is therefore already predefined on the unified element, so that the coding element sections can be jointly connected to the plug-in contact by mounting the holding plate on the housing body.

In one embodiment, it is possible to provide openings in the webs which connect the coding element sections to one another, which openings correspond to the marking regions on the housing body of the plug-in contact. If the clamping plate is mounted on the housing body of the plug-in contact, one or more openings of the clamping plate can overlap one or more marking regions of the housing body, so that the identification on the plug-in contact is provided in this way. In this case, depending on the position of the clamping plate, individual marking areas can be covered, while other marking areas can be read through one or more openings of the clamping plate, so that a specific identification can be established on the plug-in contact depending on the position.

The frame opening of the fixed frame is preferably delimited by lateral frame walls extending parallel to one another and by end side walls connecting the frame walls to one another. In this case, the receiving openings are preferably formed in two frame walls extending parallel to one another in the width direction, which differ from one another, for example, in their width (viewed in the width direction), so that in this way, in cooperation with the coding element sections on the plug-in contact, a coding is formed which ensures that the plug-in contact is mounted correctly in a well-defined orientation.

In this case, each insertion position can correspond to exactly one receiving opening on each frame wall, so that an insertion position is defined by a total of two opposing receiving openings on the opposing frame walls.

In one embodiment, the plug-in contact has a width equal to half the width of the insertion site. The two modular plug-in contacts can therefore be mounted together in an insertion position, wherein in this case the coding element sections of the plug-in contacts together form a coding element for engagement in the receiving opening corresponding to the insertion position. The coding elements for engagement in the receiving openings are thus realized by coding element sections of adjacent plug-in contacts which are jointly inserted into the insertion position, wherein the coding elements are configured by adjusting the coding element sections such that they can be inserted into the corresponding receiving openings and engage them in a form-fitting manner.

The coding element sections of the plug-in contacts to be combined with one another can be present independently of one another and can be connected, for example, independently of one another to the respectively corresponding plug-in contact. However, it is also conceivable and possible for the coding element to be formed in one piece by two coding element sections and to be connectable to a plurality of plug-in contacts which are combined with one another and are to be inserted into the insertion position. The connection between adjacent, combined plug-in contacts can thus be made by means of such a coding element.

The plug-in contact can be plugged with an electrical conductor, so that the electrical conductor is electrically connected to the plug-in contact. The plug-in contacts can be combined with one another in a modular manner by means of the retaining frame, so that a plug-in surface is formed on the plug-in connection part, which plug-in surface can be connected in a plug-in manner to a corresponding plug-in surface of the opposite plug-in connection part. For this purpose, one or more plug-in contacts may each have a plug-in section, on which electrical contacts are arranged and which can be connected in a plug-in manner to an opposing plug-in connection.

It is conceivable here for all plug-in contacts to have plug-in sections on which the contacts are arranged. However, it is also conceivable and possible for one or more plug-in contacts to have no plug-in section and therefore to be able to provide (only) electrical circuit connections of electrical lines on the plug-in contacts via a socket.

The plug socket for connecting the electrical lines is formed, for example, on a first side of the housing body of the plug-in contact, while the plug-in section is formed on a second side of the housing body facing away from the first side, for example as a plug for inserting the opposing plug-in connection or as a socket for receiving the plug of the opposing plug-in connection.

The fixing frame constitutes a plurality of insertion positions offset from each other in the width direction for accommodating the plurality of plug-in contacts. Each insertion position is provided, for example, with a spring element on the frame wall, so that the plug-in contacts can be inserted individually into the insertion position and can also be removed again from the insertion position. The fixing frame advantageously has a substantially rectangular configuration. The frame wall forms a side face along the longitudinal side face of the fixed frame, on which two opposing spring elements for locking are arranged for each insertion position.

In one embodiment, the plug connection can have a fixing frame of the type described above. A plurality of modular plug-in contacts can be inserted into the retaining frame, at least some of which have plug-in sections which can be connected to the opposing plug-in connector in the plug-in direction and on which contacts for contacting the opposing plug-in connector are arranged. Electrical, hydraulic, pneumatic or other contacts can be provided on the plug-in contact, for example. By plugging the plug-in connection with the corresponding counter-plug-in connection, a contact is formed between the plug-in contact piece fixed in the fixed frame and the corresponding counter-contact piece on the counter-plug-in connection side.

This object is also achieved by a method for configuring a plug connector assembly. In the method, at least one modular plug-in contact for forming a plug-in surface on a retaining frame is inserted into a frame opening of the retaining frame in at least one insertion position, wherein the retaining frame has a plurality of insertion positions arranged in a row in the width direction for receiving the plurality of modular plug-in contacts, and at least one frame wall extending in the width direction, which is formed with a receiving opening corresponding to the insertion positions. During insertion, the at least one modular plug-in contact engages with one of the receiving openings of the at least one frame wall by means of at least one coding element section arranged on the housing body. Before inserting the at least one modular plug-in contact into the frame opening, at least one coding element section is adjusted.

The advantages and advantageous embodiments described above for the assembly can also be applied analogously to this method, so that reference should be made to the preceding exemplary embodiments.

Detailed Description

Fig. 1 shows a schematic illustration of an exemplary embodiment of a plug connection 1 having a housing 10 and a fixing frame 3 mounted in the housing 10. In this exemplary embodiment, the electrical line 11 is introduced into the housing 10, in which case a plurality of electrical line cores can be joined together, which join into the housing 10 and thus electrically contact the contact elements placed on the fixed frame 3.

The plug connector 1 can be plugged together with the corresponding opposing plug connector 2 along the plugging direction S. The holding frame 3 of the plug connection 1 serves to accommodate modular plug contacts 4, as shown in the exemplary embodiment in fig. 2 and 3. The plug-in contact 4 is mounted on the fixed frame 3 and has an outwardly projecting plug section 40 on which contact elements 400 are arranged for plugging in and electrical contacting with corresponding counter-contact elements of the counter-plug connector 2.

As can be seen from fig. 2 and 3, the plug-in contact 4 is of modular design and can be embodied differently. The plug-in contacts 4 each have a housing body 42, which has a socket 41 on the side facing into the housing 10 of the plug connector 1, into which a conductor core 110 of the electrical conductor 11 can be inserted for electrical contact. On the opposite, outwardly directed side, the plug section 40 and the contact elements 400 arranged thereon protrude from the housing body 42.

The plug-in contacts 4 can differ with regard to the shape of the plug section 40 on which the contact elements 400 are arranged, with regard to the number of the contact elements 400 or with regard to their basic function. For example, both electrical and mechanical or pneumatic contacts can be provided by the plug-in contact 4.

The plug-in contact 4 can be mounted on the fixing frame 3 in different combinations in a modular manner. The fixed frame 3 has

frame walls

31,32 extending parallel to each other in the width direction B, which are spaced apart from each other in the depth direction Q and accommodate the plug-in contact 4 therebetween. On the end side, the

frame walls

31,32 are connected to one another by

wall parts

33,34, so that a rectangular frame with an opening 30 is formed, into which the plug-in contact 4 can be inserted along the insertion direction E.

Along the width direction B, in the embodiment shown in fig. 2 and 3, the plug-in contacts 4 have equal indexing dimensions, in particular equal widths. However, this is not necessary, as will be described below.

Receiving openings 310,320 are formed in each case on the

frame walls

31,32, in pairs opposite one another, into which receiving openings the plug-in contacts 4 with the

coding elements

43,44 can be pushed, so that the

coding elements

43,44 of the plug-in contacts 4 enter the pair of opposite receiving openings 310,320, respectively, when the plug-in contacts 4 are located in the fixed frame 3.

The receiving openings 310,320 of the opposite frame walls 31, 32-measured in the width direction B-have different widths a1, a2 (see fig. 3). This makes it possible to implement a coding which allows the plug-in contact 4 to be inserted only in a predetermined position and orientation into an insertion position 300 formed between the

frame walls

31, 32. In this way, the first coding element 43, which is narrow as measured in the width direction B, can be pushed into the receiving opening 310 in the first frame wall 31, while the second coding element 44, which is located on the opposite side of the housing body 42, can only be inserted into the receiving opening 320 in the second frame wall 32 on account of its width a 2.

Fastening points 330,331,340,341 are provided on the end-

side wall parts

33,34, which serve to fasten the fixing frame 3 to the housing 10 of the plug connector 1 and, for example, fasten the fixing frame 3, on which the plug-in contact 4 is arranged, to the housing 10 by means of a suitable screw connection.

Furthermore, connecting devices 332,342 are provided on the

end wall parts

33,34, by means of which, for example, a neutral conductor (so-called PE connection) can be connected to the fixed frame 3 and by means of which, when the plug connector 1 is connected to the counter plug connector 2, an earth connection between the plug connector 1 and the counter plug connector 2 is achieved.

In the exemplary embodiment shown in fig. 4, a total of three insertion positions 300 are formed on the fixed frame 3, each having a width B1 and being defined by two opposite receiving openings 310,320 in the

opposite frame walls

31, 32. As described with respect to fig. 3, the receiving openings 310,320 can have different widths a1, a2 and serve to provide a coding for each insertion position 300.

Each receiving opening 310,320 is provided with a spring element 311,321 with a clamping plate tensioning the respective receiving opening 310,320, respectively, for locking the plug-in

contact

4A, 4B, 4C, 4D inserted in the insertion position 300. During insertion, the spring elements 311,321 can be elastically deflected and thus pushed laterally (in the depth direction Q) to both sides, so that the plug-in

contacts

4A, 4B, 4C, 4D are kneaded in the insertion position 300 in this way.

In the exemplary embodiment shown in fig. 4, a total of four modular plug-in

contacts

4A, 4B, 4C, 4D are placed on the holding frame 3, each having a width B2, B3 which differs from the width B1 of the insertion position 400. Thus, the first plug-in contact 4A has a width B3 equal to 3.5 times the width B1 of the insertion position 300. The other plug-in

contacts

4B, 4C, 4D each have a width B2 equal to half the width B1 of the insertion position 300.

Accordingly, in the embodiment shown in fig. 4, plug-in contact 4A (having a width B3 of 3.5 times) and plug-in contact 4B (having a width B2 of half) are combined with one another and are inserted together into two adjacent insertion locations 300. Furthermore, the plug-in

contacts

4C, 4D (each with half the width B2) are combined with one another and are jointly inserted in an insertion position 300.

Fig. 4 shows the assembly formed by the fixed frame 3 and the plug-in

contacts

4A, 4B, 4C, 4D mounted thereon in a state of being assembled with one another together with the assembly formed by the fixed frame 5 and the plug-in contact 6. The plug-in

contacts

4A, 4B, 4C, 4D each have a plug-in section on which contact elements are arranged, which plug-in sections engage with one another in the fitted state and establish a plug-in connection between the components.

The different components are components of different plug connectors 1,2 (see fig. 1) and are each inserted into a corresponding housing of a

corresponding plug connector

1,2, so that the

plug connectors

1,2 can be connected to one another in a plug-in manner by plugging together the plug surfaces formed by the components.

The plug-in

contacts

4A, 4B, 4C, 4D each have a coding element section 43a1,43a2,43B, 43C, 43D, which forms a

coding element

43,44 for engaging in the receiving opening 310,320 of the

frame wall

31, 32. In order to achieve a variable assemblability of the plug-in

contacts

4A, 4B, 4C, 4D with respect to one another, the coding element sections 43a1,43a2,43B, 43C, 43D can be adjusted in particular with respect to their width, so that the

coding elements

43,44 formed by the coding element sections 43a1,43a2,43B, 43C, 43D can be adjusted with respect to their shape such that they can engage in the receiving openings 310,320 in accordance with the coding of the receiving

openings

310, 320.

This adjustability of the coding element segments can be achieved in completely different ways.

In the exemplary embodiment shown in fig. 5A, 5B, in the combination of two plug-in

contacts

4C, 4D (which, according to the exemplary embodiment in fig. 4, for example, have a half-width of the insertion position 300), the coding element is formed on both sides by coding

element sections

43C, 43D, 44C, 44D, which coding element sections are present in the pre-configuration state independently of the housing body 42 of the plug-in

contacts

4C, 4D and can be connected to the housing body 42 of the plug-in

contacts

4C, 4D in a form-fitting manner for the configuration of the plug-in

contacts

4C, 4D.

The

coding element sections

43C, 43D, 44C, 44D are each present independently of one another and are each formed by a main body 430,440 and an engagement section 431,441. By means of the engagement section 431, each

coding element section

43C, 43D, 44C, 44D can be pushed into a corresponding push-in opening 450,460 on a side wall 420,421 of the plug-in

contact

4C, 4D, so that the engagement section 431, by means of the lateral webs 432,442, forms a form-fitting engagement with the push-in openings 450,460 and thus holds the

coding element section

43C, 43D, 44C, 44D on the housing body 42 of the corresponding plug-in

contact

4C, 4D in a form-fitting manner.

In this embodiment, the engaging sections 431,441 have different depths X1, X2 on their beams 432, as viewed in the depth direction Q, and are therefore structurally different from one another. Complementary to this, the insertion openings 450,460 on the side walls 420,421 of the housing body 42 are designed so that the

coding element segments

43C, 43D, 44C, 44D can only be mounted on the respective side wall 420,421 and so that the coding determined by the

coding element segments

43C, 43D, 44C, 44D is ensured on the

different side walls

420, 421.

The insertion into the insertion openings 450,460 takes place in the width direction B, so that a positive-locking connection is established between the

coding element sections

43C, 43D, 44C, 44D and the housing body 42 of the respective plug-in

contact

4C, 4D.

In the state in which the plug-in

contacts

4C, 4D are combined with one another, the

coding element sections

43C, 43D, 44C, 44D project laterally outward from the plug-in

contacts

4C, 4D and thus form coding elements on the side walls 420,421 of the plug-in

contacts

4C, 4D, as can be seen from fig. 5A. The coding elements are formed by the combination of

coding element sections

43C, 43D, 44C, 44D on the side walls 420,421 of the plug-in

contacts

4C, 4D and engage together in the respective receiving openings 310,320 on the

frame walls

31, 32.

In the exemplary embodiment shown in fig. 6A, 6B, the engagement section 431,441 of the

coding element section

43C, 43D, 44C, 44D extends in the width direction B through the body 430,440 of the

coding element section

43C, 43D, 44C, 44D and can be pushed in correspondingly into a complementary insertion opening 450,460, which extends over the entire width of the side wall 420,421 of the body 42 of the corresponding plug-in

contact

4C, 4D.

Furthermore, the

coding element sections

43C, 43D, 44C, 44D on different side walls 420,421 of the housing body 42 can differ in the width of the body 430,440, so that coding elements of different widths are formed on

different side walls

420, 421.

In the embodiment shown in fig. 7A, 7B, the

coding element segments

43C, 43D, 44C, 44D corresponding to the different side walls 420,421 are connected to each other by a connecting element 47 with a clamping plate 470. In the mounted state on the respective housing body 42, the clamping plate 470 surrounds the housing body 42 in the form of a cover, as can be seen in particular in fig. 7A.

In this case, the

coding element sections

43C, 43D, 44C, 44D on the different side walls 420,421 of the housing body 42 can also differ in terms of the width of the bodies 430,440, so that, when the plug-in

contacts

4C, 4D are fitted to one another, coding elements of different widths are formed on the

different side walls

420, 421.

In the exemplary embodiment shown in fig. 8A, 8B, the

coding element sections

43C, 43D, 44C, 44D each have a push-in opening 433,443, by means of which the

coding element sections

43C, 43D, 44C, 44D can be pushed onto the corresponding engagement section 451,461 on the corresponding side wall 420,421 of the housing body 42 of the plug-in

contacts

4C, 4D, respectively. The insertion opening 433,443 and the corresponding engagement section 451,461 are configured complementary to one another and can be different on different side walls 420,421, so that the

coding element sections

43C, 43D, 44C, 44D can be mounted only on the corresponding side walls 420,421, respectively.

Furthermore, the

coding element sections

43C, 43D, 44C, 44D can differ in their width and thus form coding elements of different widths on different side walls 420,421 in the mounted state to one another.

In the exemplary embodiments of fig. 5A, 5B, 6A, 6B, 7A, 7B and 8A, 8B, a marking, for example a number, is provided on the body 430,440 of the

coding element section

43C, 43D, 44C, 44D, respectively, by means of which marking the plug-in

contact

4C, 4D can be identified. By selecting the

coding element sections

43C, 43D, 44C, 44D and, if necessary, replacing them, the markings on the plug-in

contacts

4C, 4D can be variably adjusted.

In the exemplary embodiment shown in fig. 9A, 9B, each

coding element section

43C, 43D, 44C, 44D has both an engagement section 431,441 and a push-in opening 433,443, which can be pushed onto a complementary engagement section 451,461 on a side wall 420,421 of the housing body 42 of the respective corresponding plug-in

contact

4C, 4D and into the

opening

450, 460.

As can be seen from fig. 9A, 9B, the

coding element sections

43C, 43D, 44C, 44D can be mounted on different plug-in

contacts

4C, 4D in a manner rotated by 180 ° relative to one another. In this case, (different) markings can be provided on the top and bottom of the

coding element segments

43C, 43D, 44C, 44D, respectively, so that the different markings can be made readable (from the top or bottom) by rotating the

coding element segments

43C, 43D, 44C, 44D.

As can also be seen from fig. 9A and 9B, the connecting device 45 has, on the side walls 420, additional raised sections 452 in the form of beams, which, when the

coding element sections

43C, 43D are mounted on the plug-in

contacts

4C, 4D (see fig. 9A), count into the width of the coding element and thus facilitate the formation of coding elements of different widths on

different side walls

420, 421. In this embodiment, no such raised section 452 is provided on the connection means 46 on the other side wall 421.

In the exemplary embodiment shown in fig. 10A, 10B, the coding element sections are connected to one another in one piece and can be mounted together on plug-in

contacts

4C, 4D which are combined with one another, in order to form a

uniform coding element

43, 44. If the

coding elements

43,44 are mounted on the assembly of plug-in

contacts

4C, 4D, the plug-in

contacts

4C, 4D are also connected to one another by the

coding elements

43, 44.

Other aspects of this embodiment are the same as the embodiment of fig. 8A, 8B.

In the exemplary embodiment shown in fig. 11A, 11B, the

coding element sections

43C, 43D, 44C, 44D are inserted via the connecting pins 434,444 into the connecting openings 453,443 on the side walls 420,421 of the housing body 42 of the corresponding plug-in

contact

4C, 4D. The

coding element segments

43C, 43D, 44C, 44D can be rotated about the rotational axis formed by the connecting pins 434,444 on the respective side wall 420,421, whereby the width of the coding element formed by the

coding element segments

43C, 43D, 44C, 44D can be varied.

In this way, the

coding element sections

43C, 43D in the state of fig. 11B form coding elements of relatively large width which can be inserted into correspondingly large receiving openings 310,320 in the fixing frame 3. In contrast, in the state shown in fig. 11B, the

coding element sections

44C, 44D form coding elements of relatively small width which can be engaged in the correspondingly small receiving

openings

310, 320.

In the embodiment shown in fig. 12A, 12B, the

coding element segments

43C, 43D, 44C, 44D are connected to each other by a clamping plate 470. In the state shown in fig. 12A, in which the contact clip is mounted on the housing body 42 of the corresponding plug-in

contact

4C, 4D, the contact clip 470 surrounds the respective housing body 42 and forms a connection with the housing body 42 on the latter.

In the exemplary embodiment shown, structurally identical clamping elements, which are part of the

coding element sections

43C, 43D, 44C, 44D, can be mounted on the plug-in

contacts

4C, 4D, wherein the clamping elements are rotated by 180 ° relative to one another on the different plug-in

contacts

4C, 4D, as can be seen in fig. 12A.

An opening 472 is formed in each clip 470, which in the installed state overlaps a corresponding marking area 454 on the housing body 42. One marking area 454 is covered by a clamping plate 470, but the other marking area overlaps a corresponding opening 472 and is visible from the outside, so that different markings on the plug-in

contacts

4C, 4D are provided depending on the state of the clamping plate element.

In the exemplary embodiment shown in fig. 13A, 13B, the

coding element sections

43C, 43D, 44C, 44D can be pushed into the corresponding push-in openings 450,460 on the side walls 420,421 of the housing body 42 of the corresponding plug-in

contact

4C, 4D by means of the engagement section 431,441. In the inserted state, the bodies 430,440 of the

coding element segments

43C, 43D, 44C, 44D rest against a raised section 452,462 which projects laterally from the side walls 420,421 on the connecting

device

45, 46.

When the plug-in

contact

4C, 4C is inserted into the corresponding insertion position 300 and in the inserted state of the plug-in

contact

4C, 4D, a force can be absorbed and transmitted at this raised section 452,462, which is formed in one piece with the housing body 42, so that the contact force is introduced directly into the housing body 42 of the plug-in

contact

4C, 4D, wherein the width of the correspondingly formed coding element can also be predetermined by the raised section.

In the exemplary embodiment shown in fig. 14, the

coding element sections

43C, 43D, 44C, 44D are formed in one piece with the housing body 42 of the respective plug-in

contact

4C, 4D, but their width can be adjusted by dividing the partial regions of the

coding element sections

43C, 43D, 44C, 44D at the target division points 435.

The concept according to the invention is not limited to the exemplary embodiments described above, but can in principle also be implemented in completely different types of embodiments.

In particular, the plug-in contact shown here is to be understood as exemplary only. Plug-in contacts for such a holding frame can have, for example, electrical, pneumatic, hydraulic or completely different types of contacts.

The number of insertion positions provided on such a fixing frame can vary. In this case, it is possible, but not mandatory, to provide each insertion point on each frame wall with a separate spring element. It is also conceivable and possible to provide a plurality of insertion positions together with a spring element connected in the width direction.

A plug-in contact of the type shown here does not necessarily have to have a plug-in section arranged thereon for plugging in with another plug-in contact of an opposing plug-in connector. It is also conceivable and possible for the plug-in contact to have (only) a socket, so that the wires can be electrically connected to one another by means of the plug-in contact.
